Orlistat: a practical UK guide
Orlistat is a weight-management capsule that reduces absorption of some of the fat in food. The practical question is whether its benefits, bowel side effects and meal routine suit you—not whether a capsule sounds easier than an injection.
Which product are we talking about?
This guide concerns prescription orlistat 120 mg. Lower-dose orlistat 60 mg is a separate pharmacy medicine, with its own eligibility checks and instructions. Do not swap doses or assume that all orlistat is prescription-only.
Who can be considered?
The Xenical 120 mg licence covers BMI of at least 30, or at least 28 with associated risk factors, alongside a reduced-calorie diet. Meeting a BMI threshold does not establish individual suitability. A prescriber or pharmacist needs your medical history and current medicines.
What does taking it involve?
The product information links doses to main meals containing fat. A missed meal or a meal without fat means omitting that dose. Use the instructions supplied with your own prescription. More capsules are not a way to cancel out a large meal.
Side effects and other medicines
Oily stools, wind with discharge and urgent bowel movements can occur, particularly with higher-fat meals. Tell the clinician about bowel, liver or kidney conditions and all medicines, including warfarin, ciclosporin, thyroid or epilepsy treatment. Ask whether vitamin supplementation or additional monitoring is needed. Persistent or severe symptoms need medical advice.
How will you know whether it is worth continuing?
The 120 mg product information sets a review point: stop treatment if at least 5% of starting body weight has not been lost after 12 weeks. Arrange that review with your prescriber rather than repeatedly buying without checking benefit and tolerability.
Questions before paying
- Which strength and brand are you supplying, and what is included in the price?
- Who checks my other medicines and answers a side-effect question?
- When is my progress review, and what happens if treatment is not helping?
- What would a realistic meal pattern look like around my working day?
Make the routine workable
Write down your usual meals before the consultation. Be honest about takeaway nights, shift work and days when you skip lunch. The aim is a plan you can actually follow. In My Timber, you can save meals, choose manageable movement and check in on progress whether or not you buy treatment through SHIFT. Medicine decisions stay with your prescriber.
